Quantitative Analysis of Physiological Targets in Ischemia Shock Rat by Dynamic State Chart Analyzer

To evaluate the feasibility of quantitative analysis of shock by dynamic state chart analyzer,a research of the physiological targets in ischemia shock SD rat was made.The results showed that after the first bleeding, BP decreased from 115.40±10.50 to 60.10±2.70 mmHg;velocity(V)slowed down from 1 135.40±11.25 to 989.23±7.32 mm per second;caliber of the small blood vessel(D)reduced from 120.00±2.14 to 79.13±1.18 μm;number(N)abated from 8 to 4 per visualrange;the pressure of central vein(CVP)descended from 7. 00±0.07 to 6.80±4.00 mmHg and blood changed its flowing state from line-like to line or grain-like.When BP has ascended to normal or so,the second bleeding was made.After that the indexes had changed as folows;BP from 108.50±5.50 to 40.40±3.20 mmHg;CVP 7.15±0.01 to 9.66±0.02 mmHg;V 76.50±23.60 to 36.72±10.20 mm per second;D 60.50±8.12 to 75.20±9.65 μm,Nincreasing and sloppy flowing could beseen.After all the blood had been returned,BP had increased temporarily,but other indexes had no change.
